HI! I am actually working with the library for arduino of RAK811 modem, for second band of us915 frecuency and ABP mode. The module works fine; but i have some doubs about "fCnt". The fCnt that i receive is always on "0". I think that maybe one of the next commands maybe restart the counter:
2- at+set_config=dev_addr:" + DevAddr + "&nwks_key:" + NwkSKey + "&apps_key:" + AppSKey?
can you tellme wich are?
@coeus I think your problem is that OS X (as well as virtually any operating system besides DOS and Windows) sends a line feed if you press enter. RAK811 original AT firmware expects DOS style line endings (carriage return, followed by line feed). Screen under OS X sends newline only. You can try CuteCom. I use it under Linux, because you can select the line endings there .
hello! I was working with this model of RAK 811 LoRa enabled chip and, tried to use this forum and the hackster one; neither had the information as i needed, so im going to try to put it clearly so everyone else can make the node work without all the hassle:
first of all you need to flash the correct firmware to the RAK811 board, this is the link where you can find all the software and the firmware to do this: https://github.com/RAKWireless/RAK811/tree/master/AT Firmware
then you shoud use an arduino MEGA if for some reason you can´t find one you can use software serial but be aware that you need to use it as a separate function to call it when necessary and for the software serial to be able to interrupt whatever the arduino is doing at the moment.
when pluging the board to the arduino bend all the pins in the right side( the one side that has the rx and tx) and then proceed to connect a jumper cable from the rx2 and tx2 of the mega(in my case i decided to use rx3 and tx3 due to space constrains on the device) or the pins that you defined as the software serial to the shield this way:
where tx3 is connected to tx pin and rx3 is connected to rx pin on the rak.
the jumpers on the board should be connected this way:
so the voltages on the arduino wont damage the shield and the commands sent by the arduino make it to the actual chip and not the serial monitor on the usb line of the arduino.
@Charles great suggestion!, actually the main circuit on the tracker with voltage meter can drain 132 uA (100% of the time); how many current your circuit can drain? (for 100% of the time and when you activate the EN pin)
We made same testing but pls note we put the antenna in vertical position on table. The performance should be fine.pls see the snapscreen! Can we resend an antenna to you for testing again if you like?
Currently, that is not my problem. What I need to do is figure out how to get the LoRa Button back to a factory default setting, so I can configure it through the serial interface. Right now, I can't communicate to the device at all.
I made a duplicate sd (and some backups) and stopped the Loriot gateway after booting the duplicate.
There was no uninstall.sh although they mentioned it.
I manually moved/renamed the /opt/lrt and rebooted.
The TTN gateway was easy to install with the link you provided.
I can swap the sd cards now to choose the network Loriot or TTN.
